Hello lperry ,
The document below explains what that error is, essentially it could be that an ALS is not ready for injection, or some other piece of hardware connected to the GC.

Hello,
From the error code this look like error 5 with red light 2 and 4 on. Axis movement failed. Either something is blocking the X movement or there is a problem with the sensor. This will require repair. Please call the response center to get…
Hi Ive got a Varian 979 leak tester, however after a few runs the fine leak test does not work. If I use "Read standard Leak" then after it fails to switch on fine leak test. Can you please point me in the correct direction. Thanks John

Hello,
Our lab currently uses a headspace-GC-FID to analyze for ethanol in blood samples. We have a multi-level, internal standard calibration curve as well as control samples at various concentrations that are analyzed in a sequence. Is there a way…
Hello, i'm a Milan university student in thesis in an analytical lab.
I'm currently trying to develop an analytical method to isolate and analyze Niaprazine in G C-FID , by using as internal standard Phenacetin . But as i know we, in this laboratory…
Ok, I've tried to condition the column three times and no improvement. I also have clipped some of the inlet end of the column and reinstalled and that did not help either. I have not checked inlet as I have not worked on them before and I don't have…
I changed my acquisition method from using front FID to back FID. I changed this in the acquisition method detector, signals, and columns sections. On my status tab, the detector is still showing front FID and the online signals is showing no options…
Hello, I have a G1321B that showed errors during the OQPV. The FSE changed the flash lamp Iand the Intensity test is OK arround 10000 counts buen the and Raman ASTM Signal/Noise fail. I want to know if there are another test to do.
